The County-Scale Economic Spatial Pattern and Influencing Factors of Seven Urban Agglomerations in the Yellow River Basin—A Study Based on the Integrated Nighttime Light Data

The integrated night light (NTL) datasets were used to represent the economic development level, and visual analysis was carried out on evolution characteristics of spatial pattern various urban agglomerations in Yellow River Basin (YRB), at a county-scale, 1992, 2005, 2018. Global Moran’s I local Getis-Ord G methods explore overall correlation cold–hot spot levels, respectively. heterogeneity influence relevant factors level municipal scale analyzed by using multi-scale geographically weighted regression (MGWR) model. results show that county-level agglomeration YRB has an obvious “pyramid” characteristic. hot spots are concentrated hinterland Guanzhong Plain, Central Plains, Shandong Peninsula agglomeration. cold junction agglomerations, “cold west east” obvious. Labor input import exporthave positive impact for each agglomeration, government force negative impact, education shows both polarization development.
